<p>The invention relates to a force sensor comprising a transducer with a measuring element operatively connected to a measuring object for generating measuring signals of a force acting on the measuring object, and two transmission channels configured to transmit mutually corresponding signals of said measuring signals independently from one another. The invention also relates to a method for testing the operational reliability of such a force sensor. To allow an easier production of the force sensor and/or to provide the force sensor with an improved operational characteristics, the invention suggests that said transmission channels are connected in parallel to the same transducer such that the transmitted signals at the output of each transmission channel can be verified. In an according testing method, a test signal is evaluated in a transmission channel in which the test signal has been injected and in another transmission channel in which the test signal has not been injected. In another testing method, the transmitted signals are compared, wherein the result of the comparison is used to assess the correctness of the transmitted signals.</p> |
